3 1. Groundwater 1.1 Installing monitoring wells It is important for the accuracy of the sampling that good-quality materials are chosen when installing monitoring wells. Monitoring wells can be installed in numerous ways. This catalogue gives the most important of these methods SA Hand-operated bailer boring auger set for heterogeneous soils This set includes various types of soil augers for reaching the groundwater level, augers for taking soil samples with minimum disturbance of the soil, extension rods, plastic tubes with steel screw thread sockets and accessories, casing tube clamps for manipulating the tubes, bailers with steel and plastic valves, casing tube platforms to enable work to be carried out more ergonomically, spare parts and various accessories. The set is delivered in two aluminium transport boxes SA Preliminary soil borings; Soil sampling; Installing monitoring wells; Suitable for borings to a depth of about 7 metres. The set is very complete; it always has the right auger for the job in hand; Works both above and below the groundwater level; Both for sinking monitoring wells and for groundwater sampling; Extremely durable, robust, lightweight tubes; Percussion platform enables the operator to push down the tubes; Contains only non-contaminating elements SA Lost cone drilling set The specially-constructed lost cone is hammered into the ground with an electric percussion hammer, which is placed on the casing. When the required depth is reached, a perforated pipe can be inserted through the tubes or sensors may be left in the bore hole, if required. Subsequently the casing can be pulled out of the soil using the 2-person operated extractor in combination with the universal casing and rod puller clamp. This set includes: an electric percussion hammer, a generator with insulation guard, striking pens, a casing shoe for the casing, steel casing, extractor, lost cones and various accessories. Installing monitoring wells with small diameters (for environmental research); Making holes for inserting explosives for seismic research; The standard set is equipped for borings to a depth of 10 metre The set is compact and can be used in many places; The lost cone makes a very straight bore hole; There is only limited friction when inserting and extracting the tubes; Sinking wells in stony soils is not a problem; Ideal in combination with DirectWell; Very complete set. Sonic drilling In addition to the methods for installing monitoring wells mentioned in this section, there is another option, that is, Sonic drilling In very soft soils, a pipe with a lost cone on its end can be pushed down to the depths which are of interest. However, other methods will have to be used if the soil in question is normal to hard. The monitoring wells may have to be sunk using augers or percussion or sonic drilling (which is much more efficient and faster). Sonic drilling is used for various applications, including the following: profiles for mineral research and archaeology; soil sampling for environmental research and railway ballast; installing monitoring wells; soil and water remediation; seismic exploration for oil, gas and minerals; rapid installation of geothermal soil heat exchangers. Eijkelkamp s subsidiary, SonicSampDrill, has been supplying advanced sonic drilling machines to customers all over the world, from Siberia to tropical Africa, for almost ten years. More information on SonicSampDrill and sonic drilling is available at All it takes for environmental research 3

4 04.19 Percussion gouge sets for heterogeneous soils Use is often made of percussion gouge augers if bore holes have to be made in hard soils that may contain layers of rubble and/or stones. In this method, sampling augers (percussion gouges) equipped with a hardened cutting head are driven into the ground with a percussion hammer. Our standard set (04.19.SC) is equipped for boring to a depth of 5 metre. This set contains a petrol percussion hammer Cobra TT. The SD and SE sets are equipped with a light electric percussion hammer (HM 1400) and a heavy electric percussion hammer (HM 1800) respectively.

6 1.3 Sampling Pumps Peristaltic pump, standard version Peristaltic pump, compact version These peristaltic pumps, which have been specially designed for use in the field, are CE certified and splash-proof. They are highly reliable sampling devices for liquids and gases and can be used in all positions. They have been designed for long-term professional use in unfavourable conditions. Chargers are available for charging the 12 V battery in the peristaltic pump. Sampling liquids and gases in the field. Lightweight, splash-proof housing of shockproof plastic; Reliable universal peristaltic pump that can create a perfect vacuum; Clearly laid out control panel with push-buttons; Safeguarded against overloading. The most significant differences between the two peristaltic pumps are as follows: Peristaltic pump, standard Clockwise and counter-clockwise rotation Memory for pump and sampling rotational speed Connections for two small 12V pumps Internal and external battery supply Peristaltic pump, compact Only clockwise rotation No memories for speeds No external pump connection Only an internal battery supply Motorised foot valve pump, standard set Foot valve pumps are intended for pumping up groundwater for analysis for the purposes of environmental research. A foot valve pump consists of a tube fitted at the bottom end with a non-return flap with a ball check. Once submerged in water, water enters the tube through the valve. If the tube is then moved up and down, making use of the inertia of the water, new water is sucked into the tube and the water is pushed upward at the same time. The motorised foot valve pump pumps from a depth of about 60 metre with standard flow inert tubes and from a depth of about 40 metre with high flow tubes. Conventional and low flow purging/sampling in a monitoring well; Permeability tests in a bore hole; Well development; Multi-level low flow sampling. Is supplied with a detachable backpack; The system is so light that it can be carried by 1 person; Ideal for use with a flow-through cell Pump accessories: tubes A broad range of tubes is available from Eijkelkamp for the pumps described in this section. These tubes for groundwater sampling vary in diameter, length, type of material and packaging. One property that our polyethylene and silicone tubes all have in common, however, is the fact that they are subjected to a strict, selective leaching procedure to determine the degree of discharge of toxicological substances to water. Our tubes are therefore of high quality and meet the standards laid down. Accessories such as tube dispensers and clamps are also available from Eijkelkamp. 6

7 12.27 Submersible pump set The submersible pump included in the MP1 set has been specially constructed for purging and sampling monitoring wells with a diameter from 50 mm. The large capacity of this pump ensures rapid purging of a measuring point. By setting the pump at a low pumping capacity, it can also be used for sampling and low flow purging. The standard set includes the following: MP1 submersible pump, cooling jacket, service set, frequency converter in case, teflon-coated cable, teflon tube with connection, hose reel cart, generator and insulation control. Purging and sampling monitoring wells.

The set contains three Gigant submersible pumps, three booster pumps, a role of extension cable, sealed shrink sleeves (to enable a waterproof cable extension), a role of polyethylene sample tube and a battery with battery charger. Both types of pumps are small centrifugal pumps with small but powerful motors. As a result they fit in narrow monitoring wells. The Gigant pump can push water up to a height of 10 metre. The booster pumps have the same capacity and, as their name implies, can be used as boosters. By connecting one or more of these booster pumps to a Gigant pump, the pressure can be increased to about 20 metre. If long cables are used (for lower depths), the voltage loss in the cable has to be compensated for by means of a higher initial voltage SA Sampling in monitoring wells. Suitable for taking samples in narrow monitoring wells; Sampling depth to about 12 m (if only the battery supplied with the set is used); The low price of this set means that it is suitable for one-off use: in this way, cross contamination is prevented SA Bladder pump set, Ø 22 mm SB Bladder pump set, Ø 42 mm These stainless steel bladder pumps are used for purging and taking samples in monitoring wells. The teflon bladder in the pump prevents contact between the sample water and compressed air. These pumps are supplied with a pneumatic regulator and tubes. The regulator restricts the delivery during purging and sampling, which keeps the turbidity low (low flow purging/sampling). This technique is attracting increasing interest world wide (with the coming NEN , this technique will become compulsory for all sampling carried out in the Netherlands) Purging and taking samples (incl. in-line filtration) in Ø 25 mm (SA) and Ø 50 mm (SB) monitoring wells to depths of 60 m (SA) and 200 m (SB).

16 3. Sediment 3.1 Floating sediment Watertrap water sampler The Watertrap has been designed to take representative samples of flowing water to a depth of about 25 metre. The samples are taken using a stainless steel device by catching a part of a water column that moves horizontally at a specific depth and at a specific time Sampling to determine the quantity of sediment carried in a stream. The sample is sealed off in the sampler by waterproof rubber rings; Can be suspended in any position, relative to the current, that may be required; The whole set is packed in a transport case Delft bottle suspended load sampler for flowing sediment This sampler is used to determine the quantity of suspended sediment in rivers and other water streams, from the surface to 0.1 metre above the soil. The sediment-containing water flows through a sampler in the form of a bottle. The shape of this sampler causes low pressure at the back, so that the water flows into the nozzle at almost the same speed as the undisturbed water current. The rapid decrease in speed in the broader part of the sampler gives the sediment the chance to settle. Determining the quantity of suspended sediment in water streams; Can be used in two ways: suspended on a cable or in a frame on the soil Easy to use; Sturdy construction; Can be used at any depth; Bronze, seawater-resistant version Arnhem bed-load transport sampler This sampler is used for measuring the suspended load of coarse sand and fine gravel in rivers and other water streams. The streamlined sampler is mounted in a frame and consists of an inlet followed by a basket of fine wire mesh. The rapid decrease in speed in the broad sample chambers results in the settling of the sediment. A tail fin on the frame keeps the sampler facing into the current. Measuring transport of coarse sand and fine gravel in water streams Simple to drop from a bridge or boat; The tail fin ensures the correct positioning; The sample can be emptied at an ergonomic working height; Can be operated by one person. 3.2 Submerged sediment (on beds of water bodies) Visibility disc (Secchi method) A simple though not very accurate manner for determining the extent of the visual depth. The visibility disc is lowered on a wire. When it is no longer visible, the depth is read off from the graduations on the wire. After the disc has been lowered another half metre, it is slowly raised. The second measurement is made when the disc again becomes visible. The visual depth is the mathematical average of the two measurements. Determining the visual depth in water. Simple to use

17 13.51 Sediment level stave De sediment level stave is part of the standard set for measuring the depth of the sediment to a depth of 4 metre. The set contains 4 sediment-measuring rods made from anodised aluminium with screw thread connections. The rods are 1 metre in length and have a diameter of 25 mm. The set also includes an elbow for taking measurements in the sediment with measuring rods from the waterside. A stainless steel grid and a core point make it possible to find the upper and lower limits of the sediment layer. For determining the depth of the upper surface of a submerged sediment layer. Can be extended to 7 metre; Elbow connection makes it possible to work from the water side; The set is supplied in a transport bag Sludge Blanket detector Sludge blanket detector with suspension hook for determining the depth of a layer of sediment or bed of a water body that gives an acoustic signal and works on an optical principle. Maximum working depth 240 cm, accuracy 2 cm, storage length 163 cm. Is supplied with storage tube and 9 Volt battery. Determining the depth of sediment layers in treatment plants; Determining (undisturbed optical method) the depth of the first layer of sediment on beds of water bodies All-in-one extendible detector; Contactless optical measurement; Very easy to use; Yes-no signal leaves no room for doubt; Lightweight Van Veen grab Stainless steel Van Veen grabs are used for taking disturbed samples from submerged sediment in lakes, rivers, etc. At the surface the jaws are opened and fixed into position using a hook, after which the grab is lowered into the water. As soon as the grab touches sediment, the hook releases the jaws. When the grab is raised on the cable, the jaws close automatically due to the lever effect of the rods. The grabs are available in various sizes, but the action of all Van Veen grabs is similar. The smaller versions are manually operated and the larger ones are lowered using a winch Taking disturbed samples of submerged sediment in lakes, rivers etc. The quickest way to ascertain an indication of the sediment type; Inert stainless steel construction Ekman grab This grab is intended for use in soft sediment that is free from plant growth. Two thin hinging flaps are open while the grab is lowered. The flaps close when a drop-weight is dropped (cable operated) or a button is pressed (rod operated). Samples can, therefore, also be taken from very soft top layers. The pressure of the sample prevents much loss of material. Nevertheless, small stones or stalks may prevent the grab from closing properly, in which case, the Vrijwit auger should be used. The grab holds 3.5 litre and the dimensions are 152 x 152 x 152 mm. A rod of 1.5 m in length is also available for the rod-operated use of the Ekman grab in shallow water Sampling in soft sediments free from debris and plant growth. The flaps overlap on closing to prevent the loss of the sample; Stainless steel construction; Equipped with drop-weight system so that sampling can be carried out at any depth All it takes for environmental research 17

18 12.42 Rod-operated multisampler The multisampler is used for the anaerobic sampling of a wide diversity of wet materials, both solid and liquid. The piston can be moved in the sample tube using the piston rod, whilst the sample tube is held stationary. This means that the original layers of the material sampled are preserved. The standard set is suitable for sampling to a depth of 5 metre. The multisampler is made from stainless steel, NBR rubber (piston) and transparent acrylic plastic (sample tube). Developed for sampling wet, solid and liquid materials; For low-budget sediment sampling Rapid, simple sampling of a wide variety of water-saturated materials; Minimum compaction of the sample; Transparent sample tube enables the immediate visual inspection of the sample; Piston ensures perfect sample length SA Beeker sediment sampler, basic set SB Beeker sediment sampler, comprehensive set SA This sediment sampler, also known as the Beeker sampler, is eminently suitable for taking undisturbed samples of submerged sediment. The samples are taken in a transparent tube and the original layers of the material sampled are preserved. As a result, clear profiles can be achieved. The standard set is suitable for use in water to a depth of 5 metre. Greater depths can, however, be sampled using the additional extension rods. There is another, more comprehensive set available that includes a discharge and partition system so that samples can be taken out and described in a highly refined, accurate manner. Undisturbed sampling of submerged sediment; Clear profiles can be achieved on the basis of the samples taken. It is not necessary to assemble and disassemble the device for every new sample; Lightweight and easy to use: many samples can be taken per day; Can be used in many different types of sediment; Piston ensures perfect sample length Free-fall corer SA The Free-fall corer is a core sampler for taking reasonably undisturbed samples from the upper layers of both consolidated and unconsolidated submerged sediment. The free-fall corer consists of a frame with strengthening ribs, a drop-weight and the core sampler itself. For environmental, soil science and geohydrological research; Primarily used when sampling with rod-operated device is problematic. Cable-operated, sampling at any depth; Very quick to use, no anchoring is required; Ball valve at the top prevents loss of the sample Peat sampler The stainless steel peat sampler is, in fact, a type of gouge auger. The peat sampler is pushed into the soil by hand. The sampling section is sealed off by a plate (fin) that can pivot around the axle in the middle of the sampler and that is fitted with a cutting edge on one side. Having arrived at the correct sampling depth the complete sampler is given half a turn clockwise (180 ). During the turning, the fin remains in position which allows the half cylinder to be filled and closed again. Suitable for semi-disturbed sampling in weak and very soft soil types No loss of sample as a result of the large closing flap; Effective for sampling young peat soils and sediments; Takes point samples at any depth; Samples can be taken above and below the groundwater level.

20 5. Telemetry (e-sense) The measurement and management of equipment is increasingly carried out from a (considerable) distance. Setting up, reading out and, if necessary, taking measurements from a location of the client s choice, are standard requirements these days. The use of the e-sense telemetry measuring system, whereby measuring results are collected by intelligent sensors such as the e+ -sensors or the Diver, enables you to do much more than simply measuring. Intelligent sensors measure independent data in the field and store these internally. Your measuring results or alarm signals are then sent to a database in your own PC (e-sense direct) via the connection with an e-sense field modem. A complete e-sense telemetry system consists of the following components: A) PC modem set; B) Field modem; C) Housing for field modem; D) e+ sensor; E) Communication cables; F) Software. A) PC-modem set You need the PC modem set for direct communication via e-sense to enable communication between your PC and the e-sense field modem. The complete set consists of a modem, a power source, an antenna, a communication cable and software. B) Field modems Four types of field modems are available.

Power source 7.5 Vdc. Can be read out and configured via the database. Installation in the field, plug and play The e-sense field modem is equipped with a display which displays the status during installation. One of the functions of the e-sense modem is, in the first instance, to determine what the best set up is for good gsm reception. The next step is to connect the sensors with waterproof connections. The e-sense modem checks whether the sensors connected work properly. If required, the current measuring values from the sensors can be checked using a laptop / The configuration of the measuring setup is sent in encoded sms messages to the database. This processes the messages and sends an acknowle dgement of receipt back to the sensors. The e-sense modem indicates that everything is working correctly and the user can close the waterproof, fraud-proof field housing with an easy mind. The advantages are as follows: Inexpensive; Flexibility with regard to the measuring parameters; A long life; Various types of sensors can be used; Alarm function; The batteries have the capacity to provide power for the entire installation for a year (or 2 years in the case of the long life versions).
